Abstract

The invention discloses a biological preparation for treating high-concentration ammonia nitrogen wastewater. Preparation raw materials of the biological preparation are prepared from the following components in parts by weight: 10 to 15 parts of chlorella DH2 algal liquid, 20 to 30 parts of pseudomonas hibiscus DT1 fermented bacterial liquid, 15 to 20 parts of bacillus megaterium NCT-2 fermentedbacterial liquid, 10 to 15 parts of acinetobacter baumannii AL-6 fermented bacterial liquid, 5 to 10 parts of photosynthetic bacteria fermented bacterial liquid, 1 to 3 parts of agar and 3 to 5 partsof polyvinyl alcohol. In addition, the invention also provides a preparation method of the biological preparation for treating high-concentration ammonia nitrogen wastewater. According to the biological preparation, ammonia nitrogen in the high-concentration ammonia nitrogen wastewater is efficiently removed by utilizing a synergistic effect of heterotrophic nitrifying and aerobic denitrifying bacteria and chlorella; further, a nitrification process and a denitrification process of the biological preparation are carried out in the same device; a procedure is simple; a different procedure combination does not need to be set, and not only is the treatment efficiency of the wastewater improved, but also the running cost is saved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a biological preparation for treating high-concentration ammonia nitrogen wastewater and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the economy and industry and the improvement of the urbanization trend of people's living, the total discharge of industrial wastewater and domestic sewage has increased year by year. As a result, the nitrogen nutrients contained in the sewage rose to become the main pollutants. The outstanding harm of ammonia nitrogen in water is to cause eutrophication of water, deterioration of water quality, and affect the ornamental and tourism value of water. In addition, ammonia nitrogen and algal substances consume dissolved oxygen in water, and fish and shrimp aquatic animals and plants will die in large numbers due to lack of oxygen. In addition, long-term accumulation of...
